Lowshelf Filter Node

Standard lowshelf filter. Frequencies lower than the frequency get a boost, or an attenuation; frequencies over it are unchanged.

Inputs

Audio The Audio line to which the filter is applied.
Frequency-control A Control input to automate the Frequency setting, in Hz, from 10 Hz to the Nyquist frequency. This input can be toggled from the Node settings panel.
Gain-control A Control input to automate the Gain setting, in dB, from -40 dB to 40 dB. This input can be toggled from the Node settings panel.

Settings

Frequency Sets the upper limit of the frequencies getting a boost or an attenuation.
Gain The boost, in dB, to be applied; if negative, it will be an attenuation.
Filter order Represents the order of the differential equation describing the filter.

Outputs

Audio The filtered audio stream.

Audio and Control lines (visualized with blue and purple, respectively) are both analogous to an analog signal. They can be used interchangeably, and, for example, an Audio output (blue) can be connected to a Control input (purple), or vice-versa.

Technical details

This Node has exactly 2 samples of latency (equals ~0.0045 milliseconds at 44.1 kHz).
